Party marriages must be approved by a committee, and to gain such approval, the man and woman in question must not demonstrate any true physical affection for one another. The goal of a marriage is to produce offspring, not to seek personal pleasure or satisfaction. In fact, certain Party organizations, including the Junior Anti-Sex League (of which the dark-haired girl is a member, as demonstrated by the crimson band around her waist), advocate celibacy and procreation through artsem, Newspeak for artificial insemination, and even suggest that children should be raised in public institutions rather than by parents.
All marriages between Party members had to be approved by a committee appointed for the purpose, and -- though the principle was never clearly stated -- permission was always refused if the couple concerned gave the impression of being physically attracted to one another. The only recognized purpose of marriage was to beget children for the service of the Party. Sexual intercourse was to be looked on as a slightly disgusting minor operation, like having an enema. This again was never put into plain words, but in an indirect way it was rubbed into every Party member from childhood onwards. There were even organizations such as the Junior Anti-Sex League, which advocated complete celibacy for both sexes. All children were to be begotten by artificial insemination (artsem, it was called in Newspeak) and brought up in public institutions. This, Winston was aware, was not meant altogether seriously, but somehow it fitted in with the general ideology of the Party. The Party was trying to kill the sex instinct, or, if it could not be killed, then to distort it and dirty it. He did not know why this was so, but it seemed natural that it should be so. And as far as the women were concerned, the Party's efforts were largely successful.
